The survey to cold storage: The survey with mailing questionnaire was made to cold storage in order to know the occupational conditions, health status of workers etc. The range of the air temperatures in cold storage is very wide. The frequent ranges of the air temperature in cold storage are -20〜-29℃ and then -30〜-39℃. The lower the air temperature in cold storage is, the shorter the working hour in cold storage every time becomes. The frequent working hour in cold storage every time are 10〜30min and then 5〜10min. Experimental study: Six subjects were exposed in a climate chamber for one hour to air temperatures of -5, -20 and -30℃ wearing cold-protective clothing. Body temperatures, performances, thermal sentation etc. were studied. The results of tapping is more susceptible to the cold air temperature than that of "bolt-removing". Subject's thermal discomfort sensation became severe during cold exposure, especially at -30℃.
